Abstract
The glucose carbon signals in the 13C nuclear magnetic resonance (NMR) spectra of hydrolyzable tannins forming anomer mixtures, which differ from each other in the locations of acyl groups, were assigned. The utility of these data was demonstrated by application to the structural assignments of recently isolated dimeric hydrolyzable tannins [e.g., camptothin A (and camptothin B (14)].
